Bearings
The intermediate was fully lubricated when
shipped from the factory. Under normal conditions,
add three shots of No. 0 lithium base grease from a
grease gun through the grease fitting (13) after
each 250 hours of operation or once each month,
whichever comes first. Do not over-lubricate. Over-
lubrication can cause the bearing to over-heat, re-
sulting in premature bearing failure.
Observe the area between the shaft and
bearing retainer (17) as grease is added. If
old grease is forced out as new grease is
added, the bearing cavity is full and should
be disassembled and cleaned immediate-
ly.
There are no provisions in the bearing cavity to
drain or flush the lubricant. The pump and interme-
diate must be disassembled to completely clean
and maintain this cavity.
Under normal conditions, change the grease after
each 5000 hours of operation, or at 12 month inter-
vals, whichever comes first. Change the grease
more frequently if the pump is operated continu-
ously or installed in an environment where variable
hot and cold temperatures are common.
When lubricating a dry (overhauled) intermediate,
fill the cavity through the lubrication fitting with ap-
proximately one third pound (0,15 kg) of grease
(approximately one-third full).
For cold weather operation, consult the factory or a
lubricant supplier for the recommended grade of
lubricant.
